Specification of Letters Patent.

Application filed May 1a, 1910. Serial No. 561,715.

To all whom it may concern Be it known that I, CHARLES C. HANSEN, a citizen of the United States, and resident of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Improvement in Oiler's,

of which the following is a specification.

- tween the pressure fluid controlling valve and the valve chest of theengine, certain of the parts being shown in side elevation and certain of' the parts in section, Fig. 2is a similar view showing the oilerlocated ndirectly in the valve chest, Fig. 3 is a dethe pin 2.

tail sectional view showing the oiler located in a passage in communication with the interior of the valve chest of'the engine, Fig.

4 is a detail side view of one form of'cartridge receiving shell, Fig. 5 represents the several parts of the cartridge disassembled,

Fig. 6 is a perspective view of the cartridge carrying box used for transportation purposes, a portion of the same being broken away toshow a cartridge located therein,

and Fig. 7 is an enlarged detail cross section through the cartridge body to more clearly illustrate its structure.

The'cartridge proper comprises a body l and its carrying pin 2, screw plug 3'and means for securing the body 1 on the pin 2, in the present instance tom-prising washers 4 and cotter pin 5. The body portion 1 is arranged to be impregnated with the lubricating oil, which body portion is herein shown as comprising a strip of fabric such as flannel or cotton and a strip of brass wire netting rolled together around By this arrangement a porous mass is provided which will contain a considerable amount of lubricating oil.

This cartridge is introcnced into a chamber or pa agg in mmmmionwith the pressure fluid supply for operating the engine so as to be sub ected to the fluctuations in pressure or, in other words, the pulsations due TlllS into the operation of the engine. troduction of the oil impregnated cartridge 1nto communication with the fluid pressure supply for the engine may be accomplished in various ways, several of which are herein illustrated and will be now described.

Referring to Fig. 1, a hollow coupling 6 1s connected to the fluid pressure supply pipe 7 and valve chest 8 of the engine. The fluid pressure supply pipe 7 is provided with the usual fluid pressure controlling valve 9. A hollow shell 10 is screwedinto the coupling 6. with one or more openings 11 at its inner end within the coupling 6 for bringing the interior of the shell into open communication with the interior of the coupling 6. The cartridge is inserted into the shell 10 and held in its position therein by the screw threaded engagement of the plug 3-with the outer end of the shell 10.

In Fig. 2-, the cartridge, with a slightly modified form of shell 10, is inserted into the valve chest 8. The hole 11 in the shell 10, is, in this instance, in communication with the motive fluid inlet passage 12 of the valve chest.

In Fig. 3 the shell 10 is disposed of and the cartridge is inserted into a chamber 13 in open communication with the interior of the valve chest through a'port 14. r

In operation, the cartridge is soaked in oil until it has become thoroughly impregnated therewith. The cartridge is then inserted into position to bring it in communication with the pressure fluid for operating a the engine. This may bedone in the man: ner shown in Figs. 1 and 2, by inserting the cartridgeiinto a shell and inserting the shell into thelpressure fluid supply passage or it may be accomplished by inserting the cartridge itself without its shell into a chamber in communication with the fluid pressure Patented July 28, 1914.

This hollow shell is provided supply passage, as in Fig. 3. When the englue is running, there are fluctuations in pressure or, in other words, pulsations iii-the pressure fluid supply passage due to the slightly reduced fluid pressure when the engine takes the full charge of the motive fluid at the beginning of its stroke. These pulsations in the fluid pressure s11 ply assage will extract oil little by little om t e cartridge ihus obtaining-a continuous supplyoi '(Ell 1n the desired quantities for the engine while-the engine is running.

I In actual practice, theproper lubrication of the engine maybe insured the fact that it can be readily determined how long one oil impregnated cartridge will last-in th'e'engine. For instance, if the operator of the engine is given three of these oil inupregnated cartridges for operating the en:

'- gine a predetermined timeand he should not return all three of these cartridges in'their dry condition after the engine has been run the predeterminedtime, then the engine has not been properly supplied with its lubrieating oil, as there is only one way that theseoil impregnated cartridges can a run dry and '-that 1s by actually, msertin'gthem into the fluid pressuresupplypassage where they can be subjected to the pulsations due to the.

operation of the lengine. A further very beneficial result by the use of these oil impregnated cartridges is that a surplus of oil cannot possibly be supplied to the engine. TlllS will insure an enormous saving in Oil and'thereby expense in the 0 eration of the engine. This economical met od of supply ing oil to the engine will also permit the I machine to he used successfully in connection' with rock drills for operating on -.free milling gold props ties Where the Waste of oil on the rock will materially reduce the amalgamation, as the quantity of oil used with my improved oilcr is so small that it will not be sullicient to affect the mercury on the plates in this Workj It is desirable that means be employed for transporting thesecartridges. I therefore employ suitable boxes 15, each arranged to contain a cartridge. he parts shown and described but not claimed herein, form the subject matter of a divisional application filed by me the 13th day of August, 1910, its I serial number being 577030.
